Schwartz told ESPN.com that Odom's family is well aware of his whereabouts and that Odom's wife Khloe Kardashian "knows exactly where he is."

Schwartz's account contradicts a TMZ.com report that said Odom went missing immediately after a failed intervention attempt. A previous TMZ.com report stated that Odom had a hard-core drug abuse problem he has battled for two years.

Scwartz did not get into details of Odom's alleged drug use but told ESPN.com "Playing in the NBA is still very much a part of Lamar's plans."

Kardashian commented on the reports through her personal Twitter account.

"Really hard to sit here and listen to people talk s--- about my family!" she wrote Sunday.
